JASPER, F BROOKLYN, NEW YORK TREADLES FOR PRESSING MACHINES AND THE LIKE Original application filed June 4, 1931,

This invention relates to pressing machines, and more particularly to such machines used in the pressing of various parts of garments during the process of manufacturing. The subject matter of this application is divided out from my original application Ser. No. 542,052 for pressing machines filed June 4th, 1931.

One of the objects of the invention is to provide a machine of the character referred to, having a steam table or buck for supporting the material to be pressed, a pivoted and movable steam heated pressing iron, means for exerting pressure on the said iron against the said buck, and means for locking the iron in the said position.

Another object of the invention is to provide means for adjusting the said pressures during the pressing operation.

A further object of the invention is to provide means for releasing the said pressure locking means.

A still further object of the invention is to so mount the pressure locking means that it may be swung in and out of operative position.

Yet another object of the invention is to eliminate a great deal of the hard labor re quired to press garments or portions thereof, so that girls may be employed to do such work instead of strong men as is necessary with the present day machine which is known as the jumper type, and in the use of which the pressers jump up and down upon a foot lever to exert the required pressure upon the garment pressed.

Another object is to produce a device of the character described in which the maximum simplicity of construction and operation is secured.

Other objects and advantages will appear as the nature of the improvements is better understood, the invention consisting substan- 1 tially in the novel arrangement and co-relation of parts herein fully described, and illus trated in the accompanying drawings, wherein similar reference characters are used to describe corresponding parts throughout the several views, and then finally pointed out Serial No. 542,052. Divided and this application filed October 3t),

to be understood from an illustrative, rather 7 than a restrictive standpoint.

The inventive idea involved. is capable of receiving a variety of mechanical expressions, one of which, for the purpose of illustration, is shown in the accompanying draw- 1 ings, in which Figure 1 is a perspective view of one form of my improved pressing machine looking from the front thereof.

Figure 2 is a side view thereof, partly in section looking from the right of Figure 1.

Figure 3 is a sectional top plan view of the pressure applying and locking means, taken on line 8-3 Fig. 2.

Figure 4: is a fragmental side viewpartly in section showing the pressure locking means in released position and Figure 5 is a fragmental sectional view taken on line 5-5 Fig. 2 showing the detent means for maintaining the pressing iron in adjusted position.

Referring now to the drawings in detail indicates a table supported on a frame 11. At the front of the table 10 there is secured a buck 12 and at the rear and to one side of the said table 10 there is secured a bracket 13 having a steam inlet pipe 14, in communication with a bore 15 in the said bracket. A

short pipe 16 is screwed into the said bore 15' and locked in position by means of a nut 17. Rotatably secured in the said pipe 16 is one end of a pipe line 18 which at its opposite end has secured thereto by means of a clamp 19 one end of a hose 20 leading into a pressing iron 21. A second hose 22 leads from the pressing iron 21 to a pipe line 23 and issecured thereto by means of a clamp 24 similar to the clamp 19. The second pipe line 23 is similarly' mounted in a short pipe section maintained in the bracket 13 and is in communication with. a second bore from which there extends a pipe line 30 leading into the buck 12. A pipe line 31 leading from the buck 12 forms a steam return to the source of supply.

A bracket 33 secured to the bottom of the table 10 and extending to the rear thereof, has pivotally mounted thereon at 34 a lever 35, the upper arm 36 of which terminates in upper and lower bearings 37 and 38. Between the said bearings there is swingingly supported on a rod 39, a bracket 40 having a slideway 41 in which there is slidably supported a slidebar 42. The said slidebar terminates at the front thereof in a hub 43 (see Figs. 1, 2 and 5) having a threaded opening 44 through which passes a threaded stud 45 terminating in a ball 46. Suspended from the said ball is a hub member 47 from the bottom of which extends a stud 48 entering into the pressing iron 21, thus forming a universal joint for the said iron. Ball bearing rollers 50 and 51 provide easy sliding means for the bar 42.

The lower end of the lever 35 terminates in an arm 55 (see Fig. 2) which is engaged by a yoke 56, the said yoke having a rod 57 extending therefrom and in engagement with a foot lever 58 pivotally mounted at 59. The said foot lever 58 is depressible against the tension of a pair of springs 60 the top ends of which are anchored at the forward end of the bracket 33 and the bottom ends pass through ears of a slotted plate 61 adjustably secured to the extreme'forward end of the lever arm 55.

Pivotally mounted at 62 on the foot lever 58 and straddling same is a toothed rack or yoke 63 which is under the tension of a pair of springs 64. Vhen the foot lever 58 is depressed the said rack will be brought into engagement with pawl 65 pivoted at 66 on the lower portion of the frame 11, a spring 67 tending to maintain the said pawl in desired position. The engagement of the rack and pawl provide locking means for the foot lever or pressure applying means.

The operation of my improved pressing machine is as follows. The iron 21 is first adjusted to about the required height above the buck 12 by means of turning the head of the screw 45. \Vhen in the above named adjusted position a pin 70 in the slide bar hub 43 will be forced into one of two slots 71 in the screw 45 by means of a spring 7 2 secured to the said hub. After this initial adjustment the foot lever 58 is depressed the iron 21 being swung down against the buck or material thereon, and the foot lever becomes automatically locked by means of the rack 63 and pawl 65.

As not all of the materials pressed are of one thickness and require different pressures of the iron, the method employed to accomplish this by the pressers employing the present day machines which have no locking means, is to jump on the foot lever and thus vary the pressure. In the present machine this jumping is eliminated, as I may vary the pressure while in the act of ironing or pressing by merely depressing the foot lever 58 further than the dot and dash position shown in Fig. 2 so that the pawl will engage on an upper tooth of the rack 63.

To release the pressure applying foot lever, I have provided a second or auxiliary foot lever 80 pivoted at 81 on the main foot lever 58, and connected by means of a slotted link 82 to therack member'63. By depressing the said auxiliary foot lever, a roller 83 at the end thereof will engage a cam surface 84 at the bottom of the said rack and cause same to swing into the full line position shown in Fig. 4. The locking rack 63 may be brought into inoperative position by swinging same about its pivot 62 and latching same in the dot and dash position (Fig. 4) by means of a link 85 pivotally secured at 86 to the main foot lever.

By referring to Figs. 1 and 2 it will be seen that the two hose carrying pipe lines 18 and 23 are connected together by means of a link 90, this connection and the fact that the said pipe lines are rotatably mounted takes all the strain 06 the hose 20 and 22 and prevents their breaking due to excessive and constant pull on them during the pressing operation.

It will also be seen by referring to Fig. 2 that when the pressing iron 21 is pressed down against the buck, the said pressure will press the bar 42 upwardly at the front thereof and lift same off the roller 50 and against the top front edge 91 of the slideway 41, and downwardly against the rear bottom edge 92 of the said slideway thus relieving the rollers 50 and 51 of all strain.

The forward movement of the pressing iron carrying bar may be limited by one of a number of removablestop pins 93 in the said bar, the particular stop utilized depending upon the length of the buck employed.

From the foregoing it will be seen that I have provided a simple and easily operable pressing machine in which the pressure applying means may be releasably locked in any desired position and additional pressure added during the pressing'or ironing operation and thus eliminate a great deal of time and labor formerly required for performing this type of Work with the existing machines) Having described my invention what I claim as new and desire to secure by Letters Patent is: V
